"The impacts of unmitigated climate change are going to cost us far more than any action." This is true, but it obscures the politics. The cost of net-zero will fall mostly on the rich, fossil-capital holders in particular, because phasing out oil and gas devalues their assets. 1/2
These past two months have seen countless Europeans losing loved ones to high temperatures, with more than 14,000 people dying during late June's record-breaking heat wave alone. Nearly a half-million people fled from approaching flames without knowing whether they would have a home to
return to, and hundreds eventually returned to ashes. Aside from the human suffering, this summer will also take a toll on Europe's
fragile economy. The cost of rebuilding from the megafires in Spain and France, as well as the blazes now raging in Greece, will run into the billions. Lost productivity due to heat is costing companies dearly; drought is destroying harvests; and power prices surge as low river levels deprive nuclear reactors of cooling water,
bringing Hungary to the brink of an energy crisis. "We're seeing already how far-reaching the impact of these events on our economy is," said Anders Levermann, a climate scientist at the Potsdam
Institute for Climate Impact Research. These costs, Levermann and other experts say, should serve as a reminder that efforts to slash planet-warming pollution are a sound investment rather than
an economic disadvantage.

II wish methane was also mentioned more often! According to the authors of 'the Methane Imperative', it has caused about half of current warming, so its role, and the potential to use is as an emergency brake, are significant! www.frontiersin.org/journals/sci...
Extract from linked text: "Why do methane emissions matter?
Methane is a potent greenhouse gas, responsible for about half of global warming since preindustrial times. Alarmingly, methane emissions have risen rapidly since 2006, with 2021 and 2022 recording the largest emissions on record. This rise is much faster than projected by models and, if not addressed, puts our ability to meet climate targets at risk. On the flip side, reducing methane is a cost-effective way to rapidly slow warming.

Methane impacts human health and agriculture too, by contributing to the formation of ground-level ozone. This harmful air pollutant causes premature deaths in adults through respiratory illness and cardiovascular disease and in children under five years old, especially in low- and middle-income countries. Ozone is also harmful to many plants and reduces crop yields."
